Zero Day Initiative Advisory 12-175

Zero Day Initiative Advisory 12-175
Posted Aug 29, 2012
Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 12-175 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of HP SiteScope. Authentication is not required to exploit this vulnerability. The specific flaw exists because HP SiteScope allows unauthenticated SOAP calls to be made to the SiteScope service. One of those calls is create() which allows unauthenticated user to create a new user account for the service. This account has access to an DownloadFilesHandler which contains a flaw that allows you to download any file from the server including the server configuration files that contains the admin credentials. This can lead to remote code execution under the context of the current process.

- -- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP SiteScope. Authentication is not required to
exploit this vulnerability.

The specific flaw exists because HP SiteScope allows unauthenticated SOAP
calls to be made to the SiteScope service. One of those calls is create()
which allows unauthenticated user to create a new user account for the
service. This account has access to an DownloadFilesHandler which contains
a flaw that allows you to download any file from the server inclusing the
server configuration files that contains the admin credentials. This can
lead to remote code execution under the context of the current process.

- -- Vendor Response:


- -- Mitigation:
Given the stated purpose of SiteScope, and the nature of the vulnerability,
the only salient mitigation strategy is to restrict interaction with the
service to trusted machines. Only the clients and servers that have a
legitimate procedural relationship with the HP SiteScope service should be
permitted to communicate with it. This could be accomplished in a number of
ways, most notably with firewall rules/whitelisting. These features are
available in the native Windows Firewall, as described in
http://technet.microsoft.com/en-us/library/cc725770%28WS.10%29.aspx and
numerous other Microsoft Knowledge Base articles.
